Methyl methacrylate (MMA) is an organic compound. This colourless liquid, the methylester of methacrylic acid (MAA) is a monomer produced on a large scale for the production of poly(methyl methacrylate) (PMMA).
1. The principal application, consuming approximately 80% of the MMA, is the manufacture of polymethyl methacrylate acrylic plastics (PMMA)
2. Methyl methacrylate is also used for the production of the co-polymer methyl methacrylate-butadiene-styrene (MBS), used as a modifier for PVC
3. Methyl methacrylate (MMA) is polymerised to make homopolymers and copolymers with the largest application being the casting, moulding or extrusion of polymethyl methacrylate (PMMA) or modified polymers
4. A major application of MMA polymers and copolymers is in surface coatings and impregnation resins to give colour fastness and weather-resistance properties to latex paints, lacquer resins and stoving enamels
